There is one thing that aliases can do that functions cannot - and that is
control how the rest of the statement is parsed.  This can be exploited to
write an alias for find that calls a function with globbing temporarily
turned off for the rest of the statement; the function then restores
globbing state after executing the real find under the hood.

But yes, other than cool hacks like that, functions are almost always
hands down more powerful than aliases.
